Impact Damage on Lightweight Sandwich Panels

Zhou, Daowu / Stronge, W.J.

Abstract Collision experiments and finite element analysis were carried out to investigate damage on sandwich panels struck by spherical missiles at small velocities. Analytical models based on either quasi-static or dynamic behaviour of structures were developed to calculate impact force during low speed impact on circular sandwich panels. The results of the analytical and numerical models and the experimental measurement were compared. The dependence of damage on both structural parameters and impact variables was investigated.
